gives H doublet (not measured), 

 gives au asymmetrie quadruplet, tire e.xtreme lines 

 of which are very tine; those on the violet side 

 are very faint; the middle ones are resp. (from 

 violet to red) 0.11 wide (this one very faint] and 

 0.135 (ifi ; the distances of the middles are resp. 

 0.07, 0.255, 0.13 f/.«, the middle between the ex- 

 treme components seeming to have been displaced 

 0.05 (ifi towards violet with respect to the line 

 with field off. 



gives an asymmetric doublet, of which the com- 

 ponent on the violet side is 0.05 n(i wide, the 

 other very narrow ; distance of the middles 0.175 ii(r, 

 the mean of these middles is not sensibly displaced 

 with respect to the line with field off. 

 gives an asymmetric triplet (doublet with satellite 

 on violet side); not measured. 

 gives an asjnnmetric quadruplet ; outer component 

 on violet side rather strong, on red side feeble ; 

 middle components stronger.

widens and fades away, not measurable. 



gives an asymmetric doublet, consisting of (from 

 violet to red) first a shade of a width of 0.29 fiu, 

 then a strong band 0.18 mi wide, then a shade, 

 and at last a faint undefined band 0.26 \x\i wide ; 

 the middle of the first component has shifted 

 0.17 \x\x towards the violet side with respect to 

 the original band 535.5, the place of the middle 

 of the second component l;>eing 535.8. 



I) With a somewhat thicker crystal they form togetlier a heavy band.
